I feel like the aim of a large number of campaigns from a certain party are specifically aimed at amping up voter apathy and wanting people to just not vote. If that's what they're afraid of, people just turning up to vote, then just sitting out the election is letting them win.

I think the problem that alot of people have is that they expect just the vote itself is all we need to do to affect change, like that's where our responsibility starts and stops and once you've voted, you can just expect everything you want to just magically happen. That's not it at all, voting is where you're trying to set the conditions to be more favorable to your point of view, but it's still up to the citizens to affect political change. It's the difference between getting your leaders to capitulate because they're predisposed to accepting your wants/needs vs having a leader who is more likely to send in the National Guard to beat you down or just actively work against your interests.

Biden may not be perfect, but he's more likely to listen and adjust his position to a sustained Democratic voter push on certain topics. If Democratic voters and activists keep pushing & protesting on something, they're more likely to get a favorable response. Contrast this to what a Trump administration will mean. Whatever demands you make are going to be completely ignored out of spite, and if anything they'll just go in the opposite direction because you're "those" kind of voters, or potentially they end up using brutal means to suppress protests.

The Trump administration actively tried to make the COVID pandemic worse because they thought it would kill more Democrats than Republicans, they were trying to get Democrats killed, maybe by just passively not doing anything, but they still tried, never forget this. It was only because Democrats listened to the science, by being smarter and taking proper precautions, that COVID ended up blowing up in Republicans faces and killing more of them. Letting them win just gives them another chance to try again, chances are not even passively the next time around.
